Monosaccharides + disaccharides Flashcards
(13 cards)
What combination gives the disaccharide maltose?
glucose + glucose
What combination gives the disaccharide lactose?
Glucose + galactose
What combination gives the disaccharide sucrose?
Glucose + fructose
How is a disaccharide formed?
A condensation reaction between two monosaccharides.
What is a monosaccharide?
A monosaccharide is a monomer that makes up a carbohydrate.
What is a mnemonic to remember what monosaccharides form maltose?
Glue Melts
(Glucose + Glucose = Maltose)
What is a mnemonic to remember what monosaccharides form sucrose?
Gluey Fruit Sucks
(Glucose + Fructose = Sucrose)
What is a mnemonic to remember what monosaccharides form lactose?
Gluey Galas Lack class
(Glucose + Galactose = Lactose)
What is a condensation reaction?
A condensation reaction is a reaction that forms a chemical bond between two molecules and eliminates one water molecule.
What is a hydrolysis reaction?
A hydrolysis reaction is a reaction that breaks a chemical bond between two molecules and uses one water molecule.
How can you remember the difference between condensation and hydrolysis?
CONDENSation
- Condense means to stick together
What kind of bond does maltose have?
Maltose has an alpha 1,4 glycosidic bond because the monosaccharide with the first carbon in the bond is an alpha glucose.
